rpm jumping??

Sorry for the delay but got it fixed. When checking sensors I went to check crank position sensor. After I unplugged it kept coming. The wire was melted in two. So I fixed it and rerouted it away from the exhaust manifold. Took awhile to find but running normal now. Thanks for the help.
